Baby staying awake at night!

Samantha

Ever since my baby turned 29 weeks on Monday he has woken up around 2/3am ive fed him and hes refused to go back to sleep but he's wingey because he's tired anyone else experienced this and can shed some light on the situation for me as I am shattered! We leave him to winge for a while in his crib but he just will not settle so I bring him in the bed with us and he just lays there staring at me!
